A KICKBACK WARNING Kickback can occur when the moving chain contacts an object atthe upperportionof the tip ofthegulde bar or when the wood doses in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guidebarcan causethechaintodig into theobject and atop the chain for an Instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator, ff the saw chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back toward the operator. Either of these re=icti0ns Can Cause io_,sof saw control which can result in serious injury. KICKBACK PATH 3. 4. 5. 6. 7. 8. 9. 10. AVOID OBSTRUCTIONS AREA Figure 2 t STAND TO THE LEFT OF THE SAW ELBOW I_.OCKED LEFT HANo -" Figure 3 roll=l, ,,,,,,H,II f ON UNDER SIDE OF HANDLEBAF_ 1. OF ReCognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to _ccidents. Never let the moving chain contact anyobject at the tip of the guide bar. Figure 1. Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Figure 2. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log or branch. Keep your saw chain sharp and properly tensioned. Followmanufacturer's chain sharpeningand maintenance instructions. Check tension at regular intervalswiththe engine stopped,neverwiththeengine running.Make sure the bar clamp nuts are securely tighter,ed after tensioning the chain. A _ or dull chain can increase the chance of kickback to occur. Begin and continue cutting ait full throttle. If the chain is moving at a slower speed, there is greater chance for kickback to occur. Cut only one log at a time. Use extreme caution when re-entering a previous cut. Do not attempt plunge cuts. Watch for shifting logs or other forces that could close a cut and pinch or fall into the chain. Use only the Reduced-Kickback Guide Bar and Low-Kickback Chain specified foryoursaw. MAINTAIN Figure 1 I I I REDUCE THECHANCE KICKBACK KICKBACK 2. NEVER REVERSE HAND POSITIONS . SECTION Kickback is a dangerous reaction that can lead to serious injury. Do not rely only on the safety devices provided with your saw. As a chain saw user, you must take special safely precautions to help keep your cutting jobs free from accident or injury. CLEAR WORKING / CONTROL Keep agood firl_ grip on the saw with both hands when the engine is running and don't let go. Figure 3. A firm.grip can neutralize kickback and help you maintain control of the saw. Keep the • fingers of your left hand encircling and your left thumb under the front handlebar. Keep your right hand completely around the rear handle whether you are right handed or left handed. Keep your left arm straight with the elbow locked. 2. Position your left hand on the front handlebar so it is In a straight line with your right hand on the rear handle when making bucking cuts. Figure 3. Never reverse right and left hand positions during any lype of cutting. 3. Stand with your weight evenly balanced on both feet. 4. Stand slightly to the left side of the saw, to keep your body from being in a direct line with the cutting chain. Figure 3. 5. Do not overreach. You could be drawn or thrown off balance and lose control of the saw. 6. Do not cut above shoulder height. It is difficult to maintain control of the saw above shoulder height. SPECIAL _ i SAFETY i SECTION i (continued) iml. ,,, .............. j i ,i_ WARNING Because a chain saw is a high-speed wood-cutting tool, special safety precautions must be observed to re(zuce the risk of accidents, Careless or improper use can cause .serious injury. 4.

This resultsi reversalofthe chainforce usedtocutwoodand causesthes to move inthe opposite directior_of chain rotation.Pine Kickback drives the saw straightback toward the opera Pull-inpuffs the saw away from the operator.Eitherreactk can result in loss ofcontrol and possible serious inju_. SAFETY SHOES ,KNOW _AVOID AHEAD Wear personal protective gear. Figure 4, Always use steel-toed safety foQtwearwith non,slipsoles;snug-fitting clothing; heavy-dutynon-slipgloves;eye protectionsuch as norvfogging, vented goggtes or face screen; an approvedsafety hardhat, and sound barriers-- ear plugs or mufflers to protect your hearing. Regular users should have headng checked regularly as chain saw noise can damage hearing. Keep children, bystanders, and animals out of the work area-- a minimum of 30 feet (10 meters). Donot allow other people or animals to be near the chain saw when startingor operatingthe chain saw. Do not handle or operate a chain saw when you are fatigued, ill, or upset; or if you have taken alcohol, drugs or medication. You must be in good physical condition and mentally alert. Chaip saw .work is strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a chain saw. To avoid Pinch-Kickback: 1, 2. 3. Be extremely aware of situations or obstructk that can cause material to pinch the top of or otf wise stop the chain. Do not cutmore than one log at a time. Do not twist the saw asthe bar is withdrawn from under-cut when bucking. To avoid Pull-in: 1. 2. Always begin cutting with the engine at full thin and the spur against the wood. Use wedges_nade of plastic or wood, (never of me to hold the cut open. HANDLE 1. 2. 3. 4. 5. 6. 7. FUEL WITH CAUTION Eliminate allsources of sparks or flame in the ar where fuel is mixed, poured, or stored. There sh( be no smoking, open flames, or work that could ca sparks." Mix and pour fuelin an outdoor area, on bare grou store fuel in a cool, dry, well-ventilated place; and an approved, marked container for all fuel purpo., Wipe up all spilled f_el before starting your., Move at least 10 feet (3 meters) away from fuel fueling site before starting the engine. Oo not smoke while handling fuel or while opera the saw. Turn the engine off and let your saw cool in a I combustible area, not on dry leaves, straw, paper: Slowly remove the fuel tank cap and refuelthe unit. Store tool and fuel in an area where fuel vapors not reach sparks or open flames from water hea electric motors or switches, furnaces, etc. OPERATE YOUR SAW SAFELY 1. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. 2. Operate the chain saw only in outdoor areas. 3. Do not operate the saw from a ladder or in a tree. 4. Position all parts of your body to the left of cut and away from the saw chain when the engine is running. 5. Cut wood only. Do not cutmetal; plastics,masonry,'nonwood bu,ding materials, etc.Do not use yoursaw to pryor shove away limbs, rootsor other objects. 6. Make sure the chain will not makecontact with anyobJectwhile startingthe engine. NeverWto stadthe saw when the gu'rdebar is in a cut or kerf. 7. Use extreme caution when cutting small size brush and saplings. Slender material can catchlthe saw chain and be whipped toward you or pull you off balance. 8. Be alert for springback when cutting a limb that is under tension so you will not be struck by the limb or saw when the tension in the wood fibers is released. 9. Do not put pressure on the saw st the end of a cut. This can cause you to lose control when the cut is completed. 10. Stop the engine before setting the saw down. MAINTAIN WORKING 1. 2. 3. 4. 5. 6. YOUR SAW IN GOOD ORDER Have all chain saw service performed by your Sears Service Center withthe e00cept_ oftheitems listedin the maintenance section of this manual. For example, if improper tools are used to remove or hold the flywheel when servicing the clutch, structural damage to the flywheel c_ occur and cause the flywheelto burst. Keep fuel and oil caps, screws and fasteners securely tightened. Keep the handles dry, clean, and free of oil or fuel mixture. Make certain the saw chain stops moving when the throttle trigger is released. Forcorrection,referto page 24 for carburetor idle adjustment instructions. Stop the saw if the chain strikes a foreign object. InsPect the unit and repair or replace parts as necessary. Disconnect the spark plug before performing any maintenance except for carburetor adjustments. 7. Never modify your saw in any way. Use only attachments supplied or specifically recommended by the n_nufacturer. 8. Always replace the handguard immediately if it becomes damaged, or broken or is otherwise removed. Keep vibrstion isolators in good condition. Peri,odically inspectisolatorsfortears, ripsor separation ofthe'rubber portion from the metal mountings. Have your Sears Service Center replace the isolatorsif worn or damaged, if Vibrationincreases orifmountsdevelopan out ofroundor swollen shape from exposure to gasoline and/or oil. it is recommended that_ isolatorsbe replaced when a failure to one occurs. 9. CARRY AND STORE YOUR SAW SAFELY 1. Handcarry the unit with the engine stopped, the Muffler away from your body, and the Guide Bar and "Chain to the rear covered preferably with a scabbard. 2. Before transporUng in any vehicle or storing in any enclosure, allow your saw to cool completely, cover the bar and chain and properly secure to avoid turnover, fuel spillage or damage. 3. Empty the fuel tank before storing the tool. Use up fuel left in the carburetor by starting the engine and letting the engine run until it stops. 4. Store in a dry area out of the reach of children and away from where fuel vapors can reach sparks or an open flame from hotwater heaters,furnaces, etc. SAVE THESE INSTRUCTIONS NOTE: Exposure to vibrations through prolonged use of chain saws may produce Whiteflnger disease (Raynaud's phenomenon). This phenomenon reduces the hand's ability to feet and regulate temperature, produces numbness and burning sensations and can cause nerve and circulation damage and tissue necrosis. An anti-vibration system designed to reduce engine vibration is recommended for those using chain saws on a-regular or sustained basis and is provided on this saw. However, an antivibration system does not guarantee the avoidance of •Whitefingerdisease. Continual and regular users must monitor closely their use of chain saws and physical condition. Notice: Refer to the Code of Federal Regulations, Section 1910.266(5); 2.5.1 of American National Standard Safety Requirements for Pulpwood Logging, ANSI 03.1-1978; and relevant state safety codes when using a chain saw for logging purposes. ii ilill ii KNOW i ii YOUR CHAIN i iiiii i i i SAW i iii A.

The internal design of the 2-cycle engine requires lubrication'of moving parts.Lubrication is provided when you use the recommended mixtureof qasoline and oiL • "Gasoline must be clean _ and not over two months old. After a short period of time, gasoline .begins _to chemically break down and will form compounds that can cause hard starting and damage in 2-cycle engines. • The correct measure of gasoline to oil is very important.Too much oit in the mixture •will foul thespark plug. I _UTION.:_J Too little oil will cause the engine to overheat and seize. • Mix the fuel thoroughly in a container since gasoline and oil do not readily combine. Do not try to mix fuel directly in the fuel tank° 3, USE THE FOLLOWING ONLY: _ 4. DO NOT USE: • BIA C)il (Boating c; Covercontainer Institute of America) tighUy and shake forone minute. d.

NOTE: The eutomatic oiler can delivermoreoilthan is required during certaintypes of cutting such as pruningor debranchingwhichrequirethesawtobe operated at a high RPM for a long time period. To avoid runningout ofchain oilbefore_runningout of '_el, Check the=oil tank:pedodicaUy. Be sure to readjustthe oiler before returning to types of cutting that requiregreater lubrication. 4; IMPORTANT POINTS TO REMEM3ER a. Prime the oil pump on a new saw or a saw that has been unused for an extended period of time. Pump the manual oiler slowlyseveral times. Startthe engine andallo_vthe chaintorun. Stop the engine and check for an even flow Of oil on the chain. Repeat this procedure untiloil is visible on the chain. b. Fill the oil tank each time you refill the fuel tank to ensure there wilt be stJfficientoil for the chain whenever you startand runthe saw. c. The saw will use about 1/2 tank of chain oil for each tank of fuel mixture. If less oil is used, check for a pluggedoilhole in the guide bar. d- it is normal tor a small amount of oil to appear under the saw after the engine stops. This is due to oil drainingfrom the bar and chainwhen not in use. USING A!

BEGIN CUTTING WITH THE AGAINST LOG,. F_ure27 i ¸ " ii iii TECHNIQUES 1. PLAN YOUR SAWING OPERATION CAREFULLY IN ADVANCE a. Clear the work area. You need a clear area all around the tree where youcan have secure footing. b. Study the natural conditions that can cause the tree to fall in a particular direction: 1.) TheWIND direction and spe_d. 2.) The LEAN ofthe tree. 3.) WEIGHTED with BRANCHES on one side. 4.) SurroundingTREES and OBSTACLES. c. Look for decay and rot.

Do not cut metal, plastics, masonry,non-wo_ buiiomgmatedais,et_ Donor useyoursawto pryor shoveaway limbs, rootsor otherobjects. b. Stop the saw if the chain strikes a foreign object. Inspect the unit and repair or replace parts as necessary. _ c. Keep the chain out of dirt and sand. Even a small amount ofdirt will quickly dull a chain and ..... thus, increase the possibilityof kickback. -. A KICKBACK WARNING Kickbackcan occur when the moving chain contacts an object at the upper pc rtion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut.

Remove dirt, stones, loose bark, hall staples, and wire from the tree where cu are to be made: g. Plan to stand on the up-hill side when cl ting on a slope. h. Plan a,,clear retreat path to the rear ar diagonal to the line of fall. Figure 28, 2, FELLING SMALL TREES -- LESS THAN 6" IN'DIAMETER a. If you know the direction of fall: 1.) Make a single felling cut on the side away from the directionof fall. 2.) Cut alithe waythrough. 3.) Stop the saw, put it down, and get away quickly on yourplanted retreat path. b. If you are not sure which way the tree will fall, use the notch method described for felling iarge trees.

FELUNG LARGE TREES m 6" DIAMETER OR MORE _ The notch method is used to cut large trees. A notch is cut on the side of the tree in the desired direction of fall. After a felling cut is made on the opposite side of the tree, the tree will tend to fall into the notch_ OFF_ WARNING NOTE: Before the felling cut is complete, drive wedges toopen up the cutwhen necess_y to controlthe directionoffal Use weedor plasticwedges but never metal, to avoid kickback and chain damage. a. Make the notchcuL Figure30. b. . C. Make the felling cut on the opposite side of the notch about 2" higher than the bottom of the notch. Leave enough uncut wood between the felling cut and the notchto form a hinge. Figure 31. NOTE: The hinge helps to keep the tree from twisting and falling in the wrong direction. d* Use a wedge ifthere is any chance that the tree will not fall in the desired direction. DON'T Check the wind. Don't cut down wind. PUT YOURSELF , Stay on the uphill side of the terrain to avoid the tree rolling or sliding downhill after it is felled. NOTE: If the tree has large buttress roots, remove before making the notch. Cut into the buttresses vertically, then horizontally. Figure 29. 1.) Cut the bottom of the notch first, through 1/3 of thediameter of the tree. 2.) Complete the notch by making the slant cut. 3.) Remove the notchof wood. Figure29 e. f. Be alert for signs that t_hetree is ready tofall: 1.) cracking sounds 2.) widening of the felting cut 3.) movement in the upper branches. As the tree starts to fall, stop the saw; put it down, and get away quickly on your planned _retreat patho g- Be ex_emely cautious with partially fallen trees thatmay be poorlysupported.When a treedoesn't fall completely, set the saw aside and pull down the tree with a cable winch, block and tackle or tractor.To avoid injurydo not cutdown a partially fallen tree with yoursaw. iN THESE Check the "Don't cut on lean side. 15 u iii iiiiiii C. i iii i BUCKING Bucking is the term used for cutting a fallen tree to the desired log size. 1. IMPORTANT ii iiiii ISTCUT PRESSURESIDE _ 4-_ POINTS a. Cut only one log atatim e. b. Cut shattered wood very carefully. Sharp pieces of wood could be flung toward the operator. c. Use a sawhorse to cut small logs. Never allow another person to hold the log while cutting and never hold the logwith your leg or foot. d. Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log. Figure 32. e. Do not cut in an area where logs, limbs and roots are tangled such as in a blown down area. Drag the logs intoa clear area before cutting by pulling out exposedand cleared logs_ first. f. Make the f_rst bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the opposite side. As the log is being cut, it wilt tend to bend. The saw can become pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log. 2.

During undercutting, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control. Figure 34 • AWARNING " _ _I Never turn the saw upside down to undercut. The saw cannot be controlled in this position. If saw becomes pinched or hung in a log, don't try to force it out. You can lose control of the saw resulting in injury and/or damage to the saw. Stop the saw, drive a wedge of plastic orwood into the cut until the saw can be removed easily.

Do not stand on laUders, platforms, a log or in any position which can cause you to lose your balance or control of the saw. DEBRANCHING MAINTAINSECUREFOOTING ,,, • Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. • Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material can catch the saw chain and be whipped toward you or pull you off balance. • Be alert for springback. Watch out for branches that are bent or under pressure as you are cutting to avoid being struck by the branch or the saw when the tension in the wood fibers is released. • Keep a clear work area. Frequently clear branches out of the way to avoid trippingover them. i_ USE COMMON SENSE o PRUNING a. Limit pruning to limbs shoulder height or below. Do not cut if branches are higherthan your shoulder. Get a professional to do the job. b. Refer to Figure38 for the pruning technique. 1 .) Undercut 1/3 of the way through the limb near the trunk of the tree. 2.) Finish with an overcut farther out from the trunk. 3.) Keep out of the way of the falling limb. .4.) Cut the stump flush near the trunk of the tree. _ILWARNING Be alert for and guard against kickback. Do not allow the moving chain to aontact any other branches or objects at the nose of the guide bar when debranching Orpruning. Allowing such contact can result in serious injury. ........ a. Always debranch a tree after it is cut down. Only then can debranching be done safely and properly. Remove small limbs with one b. Leave the larger lower limbs to supportthe tree as you work. c. Start at the base of the felled tree and work towards the top, cutting branches and limbs. Remove small limbs with one cut. Figure 37. d. Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting. e. Remove larger, supporting branch_s with the 1/3, 2/3 cutting techniques described in the bucking section. f.

NOTE: Be sure to propedy p_,_i)are the saw as describedin "1. Preparation" below,beforemaking any adjustments. -- Saw will not idle. See "2. Idle Speed Adjustment" and "3. Low Speed Mixture Adjustment." i J _WARNING Recheck idle speed after each adjustment below. The .,chainmustnotmoveatidle speed to avoid serious injury. 3. LOW SPEED MIXTURE ADJUSTMENT a. Allow engine to idle. b Turn the Low Speed Mixture Screw slowly clockwise _ until the RPM starts to drop. Note the position. c. Turnthe Low Speed Mixture Screw counterclockwise _ untilthe RPM speeds up and sta_s to drop again• Note the position.' d. Set the Low Speed Mixture Screw at the m_d_int between the two positions. 4. ACCELERATION ADJUSTMENT Ifengine dies or hesitatesinstead ofaccelerating, turn the Low Speed Mixture Screw 1/16ofatum at atime counterclockwise _ until you have smooth acceleration. 5. HIGH SPEED MIXTURE ADJUSTMENT ICAUTION: I Adjustments as small as 1/16 of a .turn can affect engine performance, It is Important totum the screw only 1/16of a turn per adjustment and test the performance of the saw before making further adjustments. a. Make a test cut. b. Adjust the High Sl_._lMixture S_'ew 1/16ofatum as follows: --CloCkwise _ ifsawsmokesorlesespower. -- Counterclockwise _ if the saw has speed out of the cut but lackspower in the cut. c. Repeat test cut. d. Continue 1/1.6of a turn adjustmentsuntilthe saw runs smoothly in cut. JCAUTION: I A too lean high speed setting (clockwise _ adjustment)willcauseenginedamage to any 2-cycle engine fror_ overheating and lack of lubrication. Never set the high speed mixture screw so far clockwise _ thatyouhave high engine speed but lack power while cutting. An effective approach follows: Turn screw counterclockwise _until engine loses power while cutting. Then, turn screw clockwise _ in 1116of a turn increments only until the engine has power while cutti_l.
